NOTE
When other electric appliances are used at the same time, to avoid triggering the circuit breaker, power saving mode
is recommended. Of course you can use power saving mode to save energy as well.
Power saving mode consumes less energy, but may not heat / cool the room as much as normal mode. (The
maximum current is limited to approximately 75 % (factory default) of the normal mode.)
To adjust the power-save settings, see “To configure the power saving settings” in Power saving mode.
Even when operation start / stop, operation mode change, or power reset is performed during the power saving mode,
the power saving mode is retained until the next operation.
